GEORGE L. PIERCE, OF MANCHESTER, NEW HAMPSHIRE, ASSIGN OR, BY MESNE ASSIGNMENTS, TO HIGH SPEED RING COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MAINE.

Specification of Letters Patent.

Patented June 18, 1907.

Application filed July 21, 1905. Renewed November 22, 1906. Serial No. 344,648.

To all whom it may concern:

Be it known that I, GEORGE L. PIERoE, a citizen of the United States, and a resident of Manchester, county of Hillsboro, State of New Hampshire, have invented an Improvement in Ring-Holders for S inning and Twisting Rings, of which the ollowing de-* scription, in connection with the accompanying drawing, is a specification, like letters on the drawings representing like parts.

In another application, Serial No. 254439, filed on the 8th day of A ril, 1905, I have shown a rail plate into which is snapped a plate for sustaining or receiving a ring that carries a traveler employed in spinning and twisting yarn.

In my present application I show a different class of ring having a peculiar two-part shell that contains a wooden annulus and a traveler, the two-part shell being constructed to be snapped into the rail plate.

Figure 1, in plan view, shows my invention detached from the usual ring rail. Fig. 2 is a view like Fig. l with the part 12 of the twopart shell removed. Fig. 3 shows the traveler with its yarn-guiding eye, and Fig. 4 is a section enlarged, in the dotted line m, Fig. 1.

Itwill be understood that the construction hereinafter to be described provides for readily removing a ring of whatever diameter is being used, and snap ing into the rail plate a ring of a difierent diameter according to the count and size of yarn to be spun. The rail plate at having a central opening a slotted at 2 for the reception of screws bywhich to attach the plate to a ring rail, and provided with a locking member or upright a having a projection a and the positioning lip a to position the two-part s ell to be described that is to be sna ped into working position into and to be held by the rail plate, are and may be as shown and described in my said ap lication.

this present invention I have illustrated the ring as composed of a two-part metallic shell 10, 12, so constructed that the part hereinafter designated as the base, may be snapped into the rail plate. The base part 10 comprises a metal plate provided with a positioning device 13 shaped substantially ike the positioning device a of the rail plate, the positioning device 13, when the twopart shell is snapped into the rail plate being overlapped by the positioning device a The base part 10 has a friction member or device 14 which is substantially like the friction member or device a of the rail plate, and said base is notched at 15 outside the positioning device 13 to embrace the positioning device a and there is a notch in the base outside the friction device or member 14 to embrace the friction device or member a so that the base with whatever it carries may be readily snapped into the rail plate and be re tained therein until the friction is overcome by inserting a screw driver or some other blade between the base 10 and the rail plate, this being done whenever it is desired to change a ring of one diameter for a ring of another diameter.

The part 12 of the two-part shell comprises a foot 17 notched at 18 to embrace the positioning member 13 of the base, and said toot has an upturned lip 19 which constitutes a friction member to co-act with the friction member 14 of the base 10 so that the part 12 of the two-part shell may be readily snapped into the base 10.

The base 10 has rising from its inner edge about the spindle opening a series of traveler rests 20, shown in Fig. 4, and said rests are embraced by a wooden or non-metallic, frictionless annulus 21 containing a top flange 21 and the exterior of said annulus fits the inner side of the circular wall 22 rising from the foot 17 of the part 12 of the two-part shell, said wall having an inturned lip or flange 23 that overlaps the top flange 21 The upper ends of the rests terminate a sufficient distance below the underside of the top flange of the wooden annulus to leave a space a little wider than the thickness of the circular body of the traveler that is provided with a thread-leading eye 31, the same being turned upwardly and crossing the edge of the flanges 21 and. 23.

The yarn being spun or twisted is led from the usual guide-eye in front of the delivery rolls, through the eye 31 and thence to the bobbin on the spindle, the bobbin receiving the yarn that is being spun or twisted, and during this operation the yarn in the eye 31 causes the traveler to be revolved, the latter revolving at a slower speed than the spindle or bobbin resulting in winding the yarn on 105 the bobbin. During this winding operation the yarn has a tendency to lift the traveler, helped by centrifugal action, so that the Weight of the circular body of the traveler is removed from the rests 20 so that the traveler moves freely in the space between said rests and the flange 21 and in this Way the friction between the traveler and ring is overcome.

Having described my invention, What I desire to claim as new is:

1.. A ring holder comprising a twopart shell, one part having a resilient positioning member to engage the other part, an inclosed frictionless annulus, and a traveler.

2. In a spinning ring, a holder comprising a rail-plate adapted to be confined to the top of a ring-rail and having a positioning device and a locking device, a ring sustaining or receiving plate having a lip, and a device coacting with the locking member of the railplate, an inclosed frictionless annulus, and a traveler.

3. The combination with a rail-plate of a two-part shell provided with a base, a frictionless annulus, and a traveler, and resilient means carried by said rail-plate between which said base may be snapped or held frictionally to confine the two-part shell to the rail-plate.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnesses.
